PROBLEM TO BE SOLVED: To moderate and soften a buffering characteristic by providing a main rebound body and an auxiliary rebound body having a smaller spring constant than the former, which are arranged in parallel, making earlier the compression start timing of the latter to the displacement of a piston rod. SOLUTION: Under the pre-condition of extention-out of a hydraulic buffer 10, an auxiliary rebound body 102 is projectively arranged near a rebound stopper 31 on the side of a piston rod 12 from a main rebound body 101. Accordingly. the compression start timing of the body 102 to the displacement of the rod 12 is set earlier than that of the body 101. Under the termination condition of extension-out of the buffer 10, the timing of the body 101 to reach the compression allowance limit is set earlier than that of the body 102 to reach a close contact length for reaching the limit. With this constitution, the buffering characteristic at the time of extension-out is moderated and softened. |
